  The SAP error message COM_PARTNER_MD808 indicates that a function type is necessary for defining a partner function in the context of partner determination in SAP. This error typically arises when you are trying to define or maintain partner functions in a business transaction (like sales orders, purchase orders, etc.) but have not specified a function type for the partner function.
  Cause:
  
  Missing Function Type: The partner function you are trying to define does not have an associated function type. In SAP, partner functions must be linked to a function type to determine how they behave in the context of the business process.
  Configuration Issues: There may be issues in the configuration settings for partner functions in the relevant application area (e.g., Sales and Distribution, Material Management).
  Custom Development: If there are custom developments or enhancements, they might not be correctly configured to handle partner functions.
  
  Solution:
  
  
  Define Function Type:
  
  Go to the relevant configuration transaction (e.g., SPRO).
  Navigate to the section for partner determination (e.g., Sales and Distribution > Basic Functions > Partner Determination > Define Partner Functions).
  Ensure that the partner function you are trying to use has a corresponding function type defined.
  
  
  
  Check Configuration:
  
  Verify that the partner function is correctly assigned to the relevant document type (e.g., sales order, purchase order).
  Ensure that the partner function is active and correctly configured in the partner determination procedure.
  
  
  
  Review Custom Code:
  
  If there are any custom developments, review the code to ensure that it correctly handles partner functions and their types.
  
  
  
  Testing:
  
  After making the necessary changes, test the partner determination process to ensure that the error no longer occurs.
